RECEIVER FOR THE rSTORAGE OF STEAM.

Specification of Letters Patent.

Patented Dec. 10, 1918.

Application filed October 6, 1916. Serial N o. 124,175.

To all cli/1,0m t may concern.'

Be it known that I, HERBERT EDWARD STEINBERG, a subject of the King of Great Britain, residing at Hampstead, in the county of London, England, have invented certain new and useful Improvements in and Relating to Receivers for the Storage of Steam, of which the following is a speciiication.

My invention relates to steam accumulators or receivers of the type used more particularly in the storage of exhaust steam from a primary engine -Which is subsequently used in a secondary engine such as a turbine.

The invention relates particularly to accumulators in which a fixed bell is provided into the interior of which the exhaust steam is supplied displacing a body of water which initially fills the bell and an annulus surrounding it, the annulus being in free communication with the bell through a space provided between the bottom of the bell and the floor upon which itis supported. A central tube is fitted to the accumulator which extends downwardly into the interior of the bell and upwardly through the tank at a distance preferably above the highest level 0f water which is reached when the accumulator is in operation. This tube contains a iioat for controlling an automatic valve situated at the upper end of the tube whereby steam may be allowed to escape or be shut oil' in the event of excessive charge or discharge of the accumulator.

The primary object of my invention is to cheapen the construction of such accumulators and to this end it comprises an improved structure wherein the water from the bell is displaced through tubes or hollow columns extending from the top to the bottom of the bell.

For a consideration of what I believe to be novel and my invention, attention is directed to the following description and the claim appended thereto.

The invention is illustrated in the accompanying drawing in which Figure 1 shows my improved steam accumulator in sectional elevation and Fig. 2 is a sectional plan thereof.

In carrying my invention into ei'ect I provide a fixed bell 1 which may be of circular or other suitable shape and as shown may be located below the level of the ground or it may be located above the ground level supported on pillars. The bottom 2 of this bell 1s closed and between the top 3 and the bottom of it I arrange one or more hollow columns l at the lower ends of which openings 5 are arranged whereby water can flow freely from the interior of the bell into the columns. The upper ends of the columns discharge into a tank 6 which may be of any suitable shape and the ioor of which is partly or wholly formed by the top 3 of the i bell. Steam is supplied to the accumulator through a pipe 7 located above the level of the water in the bell. The accumulator shown is assumed to be constructed of reinforced concrete but sheet iron or other suitable material may be used instead of reinforced concrete. The top of the bell and other parts in contact with steam and surrounded by water should be provided with a thickness of heat insulating material, such as cement or other suitable composition having low heat conductivity. The float controlled valve mechanism is not shown in the drawing as this feature forms no part of my invention.

In accordance with the provisions of the patent statutes, I have described the principle of operation of my invention, together with the apparatus which I now consider to represent the best embodiment thereof; but I desire to have it understood that the appa.- ratus shown is only illustrative and that the invention can be carried out by other means such as come within'the scope of the appended claim.

lVhat I claim as new and desire to secure by Letters Patent of the United States, is

In a steam accumulator, the combination of a casing comprising upper and lower members, a vertical wall connecting the perpheral portions of the members to hold point above said upper member, a flange them in spaced relation and form a ehamwhich surrounds the upper member and ber, vertical columns which act as supports with it forms a tank for Water, and a con* 10 or the upper member and rest on the lower duit which admits steam to the chamber.

5 member7 at least one of said Columns being In Witness whereof, I have hereunto set hollow and open at both ends and through my hand. which Water flows from the chamber to a Y HERBERT E. STEINBERG.
